This is simply a regular rope and tire
hanging down from a high location in the tree.
Go ahead and attach the rope to a small
tire so it just looks and functions like an ordinary tire swing.
Try to locate the tire close to the ground as your feedline will
need to enter through a hole drilled into the bottom of the tire
and connect to your vertical antenna wire.
The vertical antenna wire should be the
same color as the rope if possible (black rope and wire is a good
choice). The antenna should be somewhat woven into the rope strands
before installation. A matching network or remote antenna tuner
can be built right into the tire itself if desired. Don't forget
to bury some radials below the ground around the tire swing vertical
and use bury flex feed line running to the house. This design
is particularly effective if you have a 30’ tree and are seeking
to install a long vertical monopole antenna for operating in the
40m and 80m frequency range but it also works well in others.
Now stand back, take a good look at the
tire swing hanging from the tree in the backyard and please tell
me where the “antenna” is located exactly?
8. The Badminton Net Antenna.
The dipole is weaved into the netting.
The feed line connects to the center of the dipole antenna which
is built directly into the net. Feedline goes directly into the
ground below. (The feed line can run on the inside one of the
metal rod supports to hide it.) Alternatively, an inverted V antenna
is used as supports for the poles.
